The Quality Control (QC) process is iterative, and involves at least 2 staff members.

The person whose digitization is being checked performs the first round of QC: run the QC script and make repairs, rerunning it until there are no errors; and THEN do a capture-by-capture review (images: an eyeball check; audio: an auditory check). For both types of material, check metadata item numbers against the items themselves.

Do *not* wait until you have hours of QC to do, because after the first hour, you will make mistakes. This is time consuming and very detail oriented.

After the first round of QC, when you think you have it perfect, pass it to a coworker, who will go through the same process but who will give YOU the feedback to make all the repairs. Continue this cycle until the results are perfect in the view of both team members.

See Scans_folder for instructions on relabeling the Scans folder to show its progress through QC.

QC Check

QC Script

The script we use in QC can be found on the Share drive here: S:\Digital Projects\Administrative\scripts\qc\ filenamesAndDupes.pl

This program will check for correct and sequential filenames per the collection number in a Scans folder and its corresponding Transcripts folder (if there is one) as well as check for duplicate filenames. It will print out a report in the “output” folder.

If it shows errors, please rename the files accordingly and also check the metadata and trackingFiles to make sure the filename is OK in those spreadsheets. When you are done with the report file this script created, please delete it.

After you have corrected the errors, RUN THE SCRIPT AGAIN. If the script still finds errors, correct those and run it again. Keep running the script until it does not show any more errors.

You should be able to run this program by double clicking on it. You might need to associate the file type with Perl the first time you use it.

Visual Spot Check

Once you've run the programs and fixed any problems, please check images.

Open every object folder with Adobe Bridge.

Verify what you see against what's in the Metadata and the number of scans recorded on Tracking files.

Hand-off

Second QC Check

A second person goes through the exact same steps listed above. If errors are found, the team member who did the initial capture should be informed, so he or she can fix them. Those materials should then be put through the QC cycle again. The cycle can be repeated as many times as necessary, until the Second QC Check uncovers no errors or problems.
